2 Kings 4:29; 2 Kings 10:15

29Then he said to Gehazi, "Gird up your loins and take my staff in your hand, and go your way; if you meet any man, do not salute him, and if anyone salutes you, do not answer him; and lay my staff on the lad's face."

15Now when he had departed from there, he met Jehonadab the son of Rechab coming to meet him; and he greeted him and said to him, "Is your heart right, as my heart is with your heart?" And Jehonadab answered, "It is." Jehu said, "If it is, give me your hand." And he gave him his hand, and he took him up to him into the chariot.
